I tried the two above mentioned frames in the store, and the WGP has a much smoother, less sloppy feell than either of them did (they seemed basically the same) I wish that there was a hole cut out below the trigger to allow another finger to rest there so the trigger could be used with one finger, but I don't think any of the other frames really have one big enough for my finger anyway, so that is a moot point. It is very smooth, and very easy to shoot fast. It makes short stroking much harder. I could do without the little blue W on the side, but that isn't really a big deal either. The trigger pull is fairly easy to adjust, given that it isn't something you have to do more than once. There is a screw inside the grip, pointed up towards the sear, all you do is turn it until the trigger is at the desired pull.

Conclusion:

It is possible that some other grips would perform just as well, but I haven't seen them, this one works great. I would recomend it to anyone looking for a hinge trigger.
